DEVICE FOR HEATING BUILDINGS.

SPECIFCATION' forming part of Letters Patent No. 427,634, dated May 13,1890.

Application led January 31, 1889. Serial No. 298,248. (No model.)

T0 MZ rif/'wm it may concern/i Be it known that I, JOHN E. STUART, ofNewark, in the county of \Vayne and State of New York, have invented anew and useful Improvement in Devices 'for Heating Buildings, whichimprovement is fully set fort-h in the following specification, andshown in the accompanying drawings.

My invention relates to heating buildings by means of radiators iilledwith steam or hot water; and the object ot the invention is to overcomecertain difficulties attending the use of these devices and this meansof heating'.

The invention is hereinafter fully described, and the features ofnovelty particularly point ed out in the claims.

Referring to the drawings, Figure l is a vertical section of a building,showing my improved device for heating attached; Fig. 2, a plan view ofsome of the parts seen, as indicated by arrow c in Fig. l; and Eig. 3, ageneral view, on a smaller scale, of a series of rooms, serving toillustrate the advantages of the invention.

Referring to the parts, A are the walls of a building or inclosure ofany kind; B, the floor; O O, apartments of various stories, and D theboiler-room in the basement.

E is a steam-boiler of any suitable kind or pattern, and F an adjacenthot-water chamber on a level with the boiler, and connected with thelatter at the top by a steam-pipe a and near the bottom by a water-pipeZ1.

G isa pump of any kind-for instance, a steam-pump-conneeted with thehot-water chamber by a water-pipe c and with the boiler by a branchwater-pipe d. The pump is connected with the steam-space of the boilerby a steam-pipe e., extending from the steanrpipe a. These pipesdescribed are provided, respectively, with gates f, g, 71., i, and k.

Z is an outiow-pipe leading from the pump to the various radiators H,located in the apartments of the building.

n is a corresponding return-pipe leading from the radiators to the\\-ate1'clia1nber F. `Steam passing from the boiler' to the chamberthrough the pipe d above the water-line heats the water in the chamber,and the pipe l), joining the boiler and chamber at points 7L the watermay be drawn wholly .from the boiler. By this means either hot or warmwater may be forced through the radiators, according to whether theweather is cold or moderate, or as it may be desired. The cool wat-erfrom the radiators iiowing back into the chamber reduces the temperatureof 'the water contained therein, and if the gates f and g of the steamand water pipes, respectively, are closed or nearly closed the water inthe chamber may be reduced to any degree of coldness down to thetemperature of the surrounding air. This enables the operator toperfectly regulate the heat of the apartments.

It frequently occurs in practical house-heating that the iioors ofadjacent parts of a building, or of adjacent buildings to be heated fromthe same boiler, are on different levels, as shown, for instance, inFig. 3. In such cases the steam or water for heating has to be conducteddownward and upward to Various levels, and traps or pockets are formedholding dead-water, and a free circulation or flow to some of theradiators is prevented.

By using the device herein shown a steady flow of hot or warm water maybe maintained through any or all of the radiators wholly without regardto the matter of the levels at which the radiators are placed, andtrapping or pocketing water is wholly prevented. The pump forces the hotwater through all the heating-pipes or radiators back to the hotwaterchamber, there being a forced circulation through the whole.

This device is adapted equally well for heating' ordinary dwellings,business blocks, hothouses, establishments for evaporating fruit,railway-cars, boats, the.

The radiators maybe constructed so that by IOO closin g a valve o ineach the hot water will be shut off therefrom and turned directlythrough the outow pipe or conduit Z.

What I claim as my invention is- 1. In a device for heating buildings, asteamboiler and a water-chamber separate from the steam-boiler in thesame apartment With the boiler, in combination with radiators placed atdifferent levels in the building, a pump to force Water through theradiators to said Waterohamber, pipes for connecting the radiators Wit-hthe pump and the Water-Chamber, respectively, pipes connecting theboiler and the Water-chamber, one pipe being above and the other pipebeing below the Water-line of the boiler and the chamber, a pipeconnecting the pump and Water-chamber, a pipe connecting the pump andWater-space of the steam-boiler, and gates for controlling the two pipeslast mentioned, so that Water may be drawn by the pump from either thewater-chamber or the boiler, for the purpose set forth.

2. The combinatiomin a device for heating buildings, of a steam-boiler,a separate chamber for holding the Water for the radiators, a pipeconnecting the steam-space of the boiler with the space above the Waterin the Waterchamber, a pipe connecting the Water-space of the boilerwith the water-space of the Waterchamber, radiators for the apartmentsof the building, a pump to force Water through lthe radiators to theWater-chamber, a pipe connecting the pump with the steam-space of theboiler, a pipe connecting the pump with the Water-space of the boiler, apipe connecting the pump with the Water-space of the Watercllamber, anoutflow pipe connecting the pump With the radiators, and a return-pipelconnectin g the radiators With the Water-chamber at a point below thatat whichl the pump draws Water from the Water-chamber, substantially asdescribed.
